To determine the mass of an object with the maximum accuracy, it is necessary to use mass comparators. When masses have to be calibrated, the object to be determined is compared with a known reference (mass comparison).
Application example for mass comparatorTo guarantee traceability of mass with the international prototype of the kg unit, it is necessary to use mass comparators. Similarly, mass comparators are necessary to determine the gas bottle filling with a high degree of accuracy (p. ex. PR2004, AX64004). With the new generation of automated mass comparators such as a5, a100, a1000, it is not only very accurate measurements which can be performed but also at the same time productivity of the processes is considerably improved.
